Visit Sky-Watcher EVOSTAR 120 EQ3 PRO SynScan GoTo is a high-performance achromatic refractor with a motorized, computerized equatorial mount. Designed for demanding astronomers, it offers an ideal combination of optical quality, observing power and ease of use thanks to its GoTo system. Whether you're a motivated beginner or an advanced user, this instrument lets you explore the sky with precision and efficiency.
Equipped with a 120 mm diameter, this scope captures 38 % more light than a 102 mm model, The result is bright, detailed images. Its 1000 mm and its focal ratio of f/8,33 provide an excellent compromise between brightness and resolution, ideal for planetary, lunar and deep-sky observation.
The Sky-Watcher EVOSTAR 120 features an achromatic doublet, a classic design with two separate lenses that effectively reduces chromatic aberrations. Unlike a single lens, this system brings different wavelengths closer together at the same focal point, guaranteeing a sharp, high-contrast image.
The lens benefits from Multi-Coated, The result is a bright, high-contrast image, ideal for studying planetary surfaces, lunar craters and double stars. The result is a bright, precise image rich in contrast, ideal for studying planetary surfaces, lunar craters and double stars.
Thanks to its performance close to the diffraction limit, this telescope offers remarkable image quality for its diameter, enabling detailed observations at high magnification.
The telescope is supplied with two eyepieces of 25 mm and 10 mm, which can achieve magnifications of x40 and x100. Its theoretical maximum capacity is x240, ideal for exploring the fine details of the Moon and planets.
Its f/8.33 focal ratio guarantees excellent image stability at high magnification, while maintaining a good level of brightness. This makes it a versatile instrument, capable of adapting to different types of observation.
The real advantage of this configuration lies in its EQ3 PRO SynScan GoTo equatorial mount. This computerized system automatically checks in over 42,900 celestial objects, including the Messier, NGC and IC catalogs.
Thanks to its stepper motors and its micro-stepping system, the mount ensures smooth, precise tracking. Its movement speed can reach 3.4° per second (up to 800x), while guiding speed can be adjusted in several stages (0.25x to 1x).
Once correctly aligned, the frame offers a perfect pointing accuracy of up to 1 arcminute, It also features a periodic error correction function, ideal for astrophotography. It also incorporates a periodic error correction function, ideal for astrophotography.
The system is PC-compatible and the control board can be updated via the Internet, guaranteeing long-term upgradability. This mount is an ideal solution for users wishing to benefit from a high-performance GoTo system without the complexity of heavier mounts like the HEQ5 or EQ6.
The frame is supplied with a aluminum tripod stable and lightweight, equipped with an accessory tray. This structure ensures stability while remaining easy to transport.
The eyepiece holder Dual-Fit 1.25”/2” allows the use of a wide range of eyepieces and accessories, offering great flexibility of evolution. Angled transmission 1,25” ensures comfortable viewing, especially when the telescope is aimed at the sky.
The researcher 6×30 facilitates the initial location of objects, effectively complementing the GoTo system for rapid set-up.
The Sky-Watcher EVOSTAR 120 EQ3 PRO is equipped with a direct connection for SLR cameras, This is the perfect tool for capturing images of the Moon, planets and other deep-sky objects.
Thanks to its motorized mount and advanced functions, it's an excellent base from which to begin astrophotography and progress to more ambitious projects.
